iii the present instance the dropdght is shown iii connection with achandelier, but it is to he understood that certain features 'oit theinvention are not limited to this com laiiizitioii. flihe chandeliercomprises a casing or body It having upper and lower sections i and Fithat form the housing for the wind in@ mechanism of the drop-light, andaround the easing; is an annular flange or ring 3 which carries aplurality of electric lights B, chandelier including suspension chains 4that are suspended from a ceilingI support C. The drop-light D includesa lamp and a tlexilile conductor cord 5 which extends out oit the'bottom of the lower section 2 of the vcesiiig from :i Winding devicewithin vthe mism are carried by a i' ame E which, in the presentinstance, .is .made of strips of metal formed into top and bottomsections Gand 7 and side scctitms 8 and 9, the sections being fastenedlogither by screws or equivalentfasteners l0, whereby a skeletonstructure is provided. The top section 6 has side extensions 1G whichoverlap the side sections 8 and l), and these ear-forming extremities 1Gare vertically disposed and overlappedwith ears ll soldered or otherwisefastened to the bottom section 2 oi the easing A, the ears ll beingvertically slotted, and passing through the slots are screws 12 whichscrew vxditliii the 'traine and ourn'aled in bear. ing openings l5 iiithe 'side sections 8 and 9` o the it eine is a horizontal shaft 16 whichcarries the centrally disposed winding Wheel i7. Surrounding the shaftand fastened thereto by a set-screw 18 or equivalent means a sleevev of.insulation 19,41nd on this sleeve are clamped metal. collector rings 20and 2l at opposite sides of the wheel l'Z. Coperating with thesecollector rings' are metal or and 2l, respectively, which The two platesor disks of the wheel are fasare carried by holders 22. These holdershave their upper ends pivotally connected by bolts or equivalent means23 with the opposite sides of the arched portion 24 of the section 6 ofthe frame, whereby the brushes are free to move on an axis parallel withthe shaft 16. Helical springs 25 are connected withthe holders 22 andwith some fixed part of the frame, such as the top plate 13, as shown inFig. 2, and these springs exert a pull in a direction to maintain thebrushes firmly against the collector rings. The brushes 2Oa and 21a areconnected in circuit by wires 20b and 21".

' The wheel 17 comprises a pair of disks 26 faced on both sides withpieces of insulation 27, and the edges of the disks are bent oppositelysofas to form a flaring periphery for guiding the cord 5 and preventingwear thereof during winding and unwinding.

tened to a hub ring 28 by a screw 29. The lamp cord 5 is made up of apair of conductors 30 and 31 which pass out of openings in the disksofthe wheel Vand are connected respectively with the collector rings 2Oand 21. @ne of these openings 32 is shown in Fig. 2, the other openingbeine' direetly-behind it, and the extremities of the conductors are'fastened by screws 33 with the collector rings. The conductor cord isof fiat cross-section, as shown in Fig. 1 andit'is of such width as tofreely enter between the side disks of the wheel, and the convolutionsofthe conductor will all lie in a single plane, whereby there is no dangerof the cord conductor binding and interfering with the from beingexerted on the terminals of the conductors where they are fastened bythe screws 33 to the collector rings', a strain device is provided. Thisdcvicein the present instance is shown as a flexible element 34 whichpasses through openings 35 in the disks of the wheel, the element beingformed ,into a knot or enlargement 36 at one end to prevent it frombeing drawn through the adjacent opening 35; and a knot 37 is formed atthe opposite side of thewheel, and the ends 38 of the flexible elementor tape 34 are engaged under a spring clip or finger 39 extendingYradially of the wheel and fastened by a screw 40 to the collector ring20. This strain-taking device 34 is, as shown in Fig. 2, about onehundred and twenty degrees displaced from the openings 32 out of whichthe conductors pass from the wheel to the collector rings, and thus whenthe cord conductor is fully unwound the strain is taken en- -tirely bythe device 34, and there is no danger of the conductors being pulled outof electrical connection with the collector rings.

The winding of the cord on the wheel is effected by a spiral spring 45which has its proper operation. To prevent a strainv 3. The wheel outerend 47 fastened to a drum 48 which is loose on the shaft 16. This drumhas in its periphery teeth 49 adapted to engage with spring pawls 50carried by flanges 51 on a disk 52, this disk being disposed adjacentthe drum 48 and having its flanges 5l fastened to the side section 9 ofthe supporting frame E. By turning the drum 48 in an anti-clockwisedirection, Fig. 3, the spring 45 can be adjusted to the proper tension,whereby the drop-light will be fully raised by the spring. This springis so arranged that when the wheel 17 turns during the un winding of theconductor cord, the spring will be tightened to thereby raise the droplight when the wheel is released.

. A stop catch is employed for preventing the wheel 17 from turninor andwinding the conductor cord when the dJrop-light has been lowered to thedesired position. The catch is in theform of a lever 53 fulcrumed at 5%on one side of the lower section 7 of the frame E, and this lever isformed with a lug 55 that is adapted to engage in any recess 56 formedbetween teeth 57 in the periphery of one of the wheel disks. This leverhas attached to opposite extremities pull chains 58 and 59,respectively, whereby the catch or lever can be rocked to engage ordisengage the winding wheel..I A helical extension spring 59 has itsupper extremity connected with upwardly-extending arms 60 on the catchor lever and its lower end is anchored at 61 on a suitable part of theframe ll. The spring is adapted to occupy a posit ion with its axisdisposed to one side or the other of a dead center line passing throughthe pivot or fulcrum 51 and the anchored lower end of the spring at thepoint Gl, whereby the catch will be held by the spring in either lockingor unlockingposition. By pulling downwardly on the chain 58 the catch isreleased so that the wheel will turn and wind up the cord. By pulling onthe chain 59 the catch is thrown into engagement with the wheel andenters the nearest recess 56. To retard the rotation of the windingwheel spring the top plate 13, with the extremities of the str1p bearingagainst the periphery of that flange or disk of the wheel other than thedisk haviiw the recesses 56, as shown in Fig, has spaced recesses 64 inits periphery in which the spring brakes are adapted to engage andthereby assist in retarding the movement of the wheel. The tension ofthe spring brakes may be adjusted by screws 65 arranged in theextremities of the arcuate top piece 13, and the inner ends ofthese'screws are adapted to engage with the spring brakes to bow thesame more or less and thereby vary the tension.

To insure the centering of the mechanism in lll all

menaces the casing of the chandelierthe bottom et the iframe E has acircular horizontal plate 66 fastened to the bottom thereof, and thisplate engages in the approximately heinispherical bottom part of thecasing section 2, as shown in llig.. l. rlhis centering plate 66 has anopening 67 through which the cord conductor 5 extends, and the cordconductor is guided by a pulley 68 journaled in the lower part oi' thetraine E in such po sition that the pulley is tangential to a verticalline passing through the axis of the windingA Wheehns clearly shown inFig. 2.

The pull chains 58 and 59 are fastened to. the catch or lever 53 byineens of the said lever having its upper edge provided with a verticalrecess 69, and a link 70 of the chain is inserted in the recess andretained therein by a U-shaped Wire or staple 7l which is passedhorizontally through the catch, and `the ends 72 of the staple are bentbackn wardly, as clearly shown in Fig. e. The chain is ol that typeconsisting ot' hollow spherical links 73 connected by the straightdouble-headed links 7l. l
